BNZ Car Insurance NZ 2026: Review, Cover, and Claims
BNZ is one of New Zealand's oldest banks, founded in 1861 and now owned by National Australia Bank. Alongside everyday banking, BNZ has long offered general insurance under the PremierCare name. What many Kiwis don't realise is that BNZ doesn't underwrite those policies itself. Its car, home, and contents insurance are all underwritten by IAG New Zealand Limited, the country's largest general insurer, which holds an AA (Very Strong) financial strength rating from Standard & Poor's.
That distinction matters in 2026, because PremierCare is being retired. From 3 January 2026, existing PremierCare policies are transitioning to new IAG-branded policies at each customer's next annual renewal. The rollout takes around 12 months. This review covers what BNZ car insurance looks like today, what's changing, and how to check whether you're getting fair value.

1. The 2026 Rollover: Will Your Premium Go Up?
PremierCare is on its way out. From 3 January 2026, BNZ car insurance policies have been renewing onto a new IAG wording, with the full transition rolling out over about 12 months. Same underwriter. Same three cover tiers. Completely rebuilt pricing.
The old discount stack is gone on the new policies: multi-policy, no claim, under-25, annual payment, security system, all five binned. In their place, IAG now sets one personalised price upfront based on your risk profile (the car, the address, the excess, the claims record, the drivers).
Will you pay more or less? It depends on who you were. Stack-the-discounts customers are most at risk of a rise at renewal. Higher-risk drivers who used to pay close to the base rate could quietly come out ahead.
Either way, this is the renewal worth actually reading before you click accept. It's also part of a wider industry shift, including Tower's move to risk-based pricing.
2. What BNZ Car Insurance Actually Covers
BNZ offers three cover levels, with scope increasing at each step. All three are underwritten by IAG, which means the wording, claims process, and cover quality are IAG's, not BNZ's. The bank is the shopfront; IAG is the insurer.
Cover Level | What It Covers |
Comprehensive | The broadest cover. Includes accidental loss or damage to your own car (accidents, weather, vandalism), plus fire, theft, and third party liability for damage you cause to others' vehicles or property. |
Third Party, Fire & Theft | Covers damage you cause to someone else's vehicle or property, plus loss or damage to your own car from fire or theft. Crash damage to your own car is not covered. |
Third Party Only | Covers damage you cause to someone else's vehicle or property. Your own car is not covered for any reason. |
Under the new IAG policies, a handful of benefits that used to be automatic are now optional extras. That's a double-edged sword. If you don't need a particular benefit, you can drop it and save. But it also means the cover you assumed was included might not be unless you actively keep it. Read the Policy Wording and Change Summary at renewal so there are no surprises if you ever need to claim.
Not sure which cover level fits? Our Comprehensive vs Third Party Fire & Theft vs Third Party guide walks through when each one makes sense for different car values and driver situations.
3. What Will It Actually Cost You?
Because pricing is now personalised, there's no single sticker price we can quote. Your premium depends on what you drive, where you live, your age and driving record, the excess you pick, whether you exclude under-25 drivers, and any optional benefits you add. Two BNZ customers in the same postcode can easily see quotes hundreds of dollars apart.
What we can tell you is what Kiwis are actually paying. According to our Q1 2026 Quashed Index, the national average comprehensive car insurance premium is $1,267 a year ($106 a month). Auckland drivers pay around $1,478, Canterbury $1,166, and Wellington $1,115. In Q1 2026, 81% of Kiwis who ran their car insurance through the Quashed Market Scan found a cheaper policy, with an average saving of $377 a year. With the old BNZ discount stack gone, the case for shopping around has only got stronger.
4. How to Get a Quote from BNZ
Most NZ insurers let anyone jump on their website and get a quote in a couple of minutes. BNZ isn't one of them. There's no public quote form, so you've got two main options.
The main online route is through your BNZ app or Internet Banking. Log in, select Apply Now, then Insurance. Quick if you're already a BNZ customer, not an option if you aren't. The other option is to call IAG directly on 0800 808 618, the team that handles all BNZ insurance enquiries, quotes, and policy changes. You can also request a callback through the BNZ website.
Whichever route you take, have your vehicle details (make, model, year, registration), address, and driving history ready. If you're shopping against another insurer, bring your current policy schedule so you can compare on matching excess and cover levels.
5. If Something Goes Wrong: Making a Claim
Claims are where insurance actually earns its keep. With BNZ, everything runs through IAG. Even though you bought through the bank, lodgement, assessment, and payout are all handled by the insurer.
If you've been in an accident, first make sure everyone is safe and call the police if a crime is involved. Then lodge the claim as soon as you can. Start it online at iagnz.custhelp.com/app/bnz, call 0800 248 888, or email bnzclaims@iag.co.nz. Have your policy number handy, plus a description of what happened, photos if you have them, and (if another driver was involved) their name, registration, and insurer. Independent witness details help too.
One word of warning: don't admit fault at the scene, don't offer to pay the other party, and don't authorise non-emergency repairs before IAG confirms your claim. These are the most common ways Kiwis accidentally reduce their payout or get a claim declined outright.
6. The Good and What We Don’t Like
What BNZ Does Well
The cover is underwritten by IAG, the country's largest general insurer, with an AA (Very Strong) S&P financial strength rating. If you already bank with BNZ, your insurance sits in the same app and login, with an IAG dashboard for adjusting excesses, sums insured, and optional benefits without picking up the phone. The new policy wording is easier to read than the old PremierCare one, and paying fortnightly or monthly no longer costs more than paying annually.
Compare More Carefully
There's no public online quote, so price-shopping takes effort. The multi-policy, no claim, under-25, annual payment, and security system discounts are all gone, which is a real loss for Kiwis who used to stack them. Distribution and claims are split between BNZ and IAG, which can feel disjointed once you're past sign-up. IAG also underwrites AMI, State, and NZI, so the same underwriter sits behind several brands, each with its own policy wording, features, and pricing. Comparing across them takes a closer read of what's actually covered, not just a glance at the bottom-line price.
7. So, Is BNZ Car Insurance Worth It?
Short answer: it's a legitimate product with strong underwriting, and for existing BNZ customers it's a genuinely convenient option. The long answer comes with a caveat. Because IAG also underwrites AMI, State, and NZI, the same insurer sits behind several brands, each with different policy wordings, features, and pricing. You might find similar cover at a very different price through another IAG-backed brand, or a better fit with a different underwriter altogether. Throw in the fact that the old discount stack is gone, and the case for quietly rolling over your renewal has weakened.
A free Quashed Market Scan takes under two minutes and checks your BNZ quote against the rest of the NZ market. If BNZ is your best option, you'll see it at a glance. If not, you'll know exactly how much you're leaving on the table.

Who underwrites BNZ car insurance?
BNZ car insurance is underwritten by IAG New Zealand Limited, the country's largest general insurer. BNZ distributes the product as IAG's agent, which means IAG sets the pricing, writes the policy wording, and handles every claim. IAG holds an AA (Very Strong) financial strength rating from Standard & Poor's.
What is replacing BNZ PremierCare insurance?
From 3 January 2026, PremierCare has been progressively retired. At each annual renewal, existing PremierCare policies move to new IAG-branded policies simply called Car Insurance, Home Insurance, Contents Insurance, or Landlord's Insurance. The full rollover is expected to complete around January 2027. PremierCare is no longer available to new customers.
How do I get a BNZ car insurance quote online?
BNZ does not have a public online quote form that just anyone can use. To get a quote online, log in to the BNZ app or Internet Banking, select Apply Now, then Insurance. If you're not a BNZ customer, call IAG on 0800 808 618 or request a callback through the BNZ website.
What is the BNZ car insurance claims number?
Claims on BNZ car insurance are handled by IAG. Call 0800 248 888 or lodge your claim online at iagnz.custhelp.com/app/bnz. You'll need your policy number, details of what happened, and any supporting photos. For general enquiries or policy changes, call IAG on 0800 808 618.
Does BNZ car insurance have a no claims discount?
Not under the new IAG policies. On PremierCare, BNZ offered a no claim discount, along with multi-policy, under-25, annual payment, and security system discounts. All five have been removed on new and renewing policies from 3 January 2026. Pricing is now personalised upfront based on your individual risk.
Does BNZ car insurance include roadside assistance?
Not automatically. BNZ Roadside Rescue is an optional extra that can be added to any BNZ car insurance policy. It's provided by First Rescue (part of IAG) and includes five free callouts per year, with extra callouts charged at $50 each. Call IAG on 0800 808 618 to add it to your policy.
Is BNZ car insurance the same as AMI, State, or NZI?
Same underwriter, different products. IAG underwrites BNZ, AMI, State, and NZI, so they share a parent insurer. However, each brand has its own policy wording, features, benefits, and pricing, so they are not interchangeable. It's worth getting quotes from more than one before you commit.
